Question

find domain and range

Answer 1

$\sqrt{25 - x {?}^ {2} } = 25 - x = - x = - 25 \\ x = 25$

Answer 2

Answer:

$\mathfrak{Domain}$

$\boxed{5}$

______________________________

$\mathfrak{Range}$

$\boxed{{x∈R : x<5}}$

_________________________________

Step-by-step explanation:

Well let y be a number for which :

$y=\sqrt{25-x^2}$

The value of y should be more than 0 in order to find the domain..

$\sqrt{25-x^2}>0$

$\implies 25-x^2>0$

$\implies x^2<25$

$\implies x<\pm5$

We neglect the negative value.

The domain of the function is  :- $5$

The range of the function will be:

${x$∈$R : x<5}$

Hope it helps you
